CULTlVATOR- SPECIFICATION forming part of Letters Patent N 0. 775,906, dated November 22, 1904.

Application filed April 25, 1904:- Serial No. 204,685. No modelfi To all whom it may concern:

Be it known that I, ANDERS H. KOPPERUD, a citizen of the United States, residing at Byron, Contra Costa county, State of California, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the same.

The hereinafter-described invention is designed for use more particularly in connection with side-draft colter-disk cultivators, the object of the invention being to provide means for taking up or compensating for the end thrust of the axle carrying the row of colterdisks, whereby undue strain is removed from the cultivator-frame and the axle for the colter disks held in proper position during the work ing of the cultivator.

To comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein-- Figure 1 is a broken top plan View of a colt-er-disk cultivator disclosing one row of colter-disks, the cross-beam pivoted to the frame of the cultivator, from which cross-beam the axle for the colter-disks is suspended, and the take-up mechanism for the end thrust of the suspended axle. Fig. 2 is a broken front view in elevation of the cross-beam and axle suspended therefrom carrying the colterdisks, one of the anglebrackets for holding the case-hardened shoe against which the free end of the axle works being sectioned, a portion of the cultivator-frame which extends through the guide-bracket of the pivoted cross-beam being sectioned; and Fig. 3 is an end view of the take-up mechanism for the end thrust, the said mechanism being illus trated attached to the cross-beam from which the colter-disks axle is suspended.

In the drawings the numeral 1 is used to indicate any suitable form of frame for a cultivator, and 2 the pole connected thereto. This frame supports the axle 3 for the row of colterdisks 4, only one axle and one row of colterdisks being disclosed in the present case, which axle 3 is suspended from a cross-beam 5 by means of the standards 6, Fig. 2 of the drawings. Said axle Works in bearings 6 of said. standards.

The cross-beam5 is attached near its inner end portion to the frame of the cultivator by the hinged joint 7, Fig. 1 of the drawings, its outer or free end portion being connected to the said frame by means of a guide or stirrup plate 8.

To the outer or free end of the pivoted cross beam 5 is attached the depending brackets 9, which brackets near their lower end carry the case-hardened shoe 10, which shoe is detachably secured to the inner face of said brackets in any suitable manner, preferably by screwbolts 11.

To the outer face of the brackets 9, preferably a slight distance above the line of the upper edge of the case-hardened shoe 10, is attached a brace or strengthening plate 12, the outer ends of which are secured to a plate 13,

attached to the free-end portion of the cross- I beam 5 by means of the tie-rods 14C. The upper ends of these tie-rods pass through holes in the upset edge of the tie-rod plate 13, being held by heads 15. To the lower screwthreaded end of the tie-rods 14 are secured the nuts 16, the tightening of which through the medium of the brace or strengthening plate 12 forces the brackets or standards 9 inward, so as to cause the case-hardened shoe 10 to bear firmly against the free or outer end 17 of the axle 3, which works against said shoe. By means of the adjustment thus permitted the tie-rods 14 wear of the case-hardened shoe 10 is compensated for. When the said case-hardened shoe has become worn out, the same is removed and a new one inserted in place thereof.

The mechanism for swinging the cross-bea1n 5 to change the position of the row of colterdisks is not illustrated in the present case, inasmuch as any suitable form of lever mechanism may be employed for this purpose.

Inasmuch as the take-up mechanism for the end thrust of the axle is mounted. to swing with movement of the hinged or pivoted crossbeam 5, it is apparent that the case-hardened shoe 10 at all times bears firmly against the said axle and prevents loose play thereof.

Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, 'is

In a colter-disk cultivator, the combination with the frame thereof, of a cross-beam pivoted at one end to the frame, an axle depending' from the cross-beam, of colter-disks on the axle, of depending supporting-brackets carried by the freeend portion of the crossbeam, a wear-shoe against which one end of the axle Works removably secured to the inner face of the brackets, a brace-plate attached to the brackets, and adjustable connection between the brace-plate and the crossbeam.

In Witness whereof I have hereunto set my hand.
